If they are too small to take even baby brine shrimp or baby copepods, I would suggest obtaining rotifers if you want the fry to survive. Be sure to mix some mysis shrimp into the diet of the adult pipefish as well.

If you can get em down there tigroprius californicus is a great little super easy to breed critter to feed to newly hatched fry.

If you cant get em down there, let me know. I breed em in garage and can harvest more from the coast line here any time I want. I would be more than happy to ship you some. They seem to tolerate temperature changes and salinity changes very well, although the shipping may be more than its worth.

Check for these guys in the upper splash zone above the high tide line next time you are at the coast down there, you may find some

I have 5 adult in the DT They seem to be happy enough Ive been feeding them brine shrimp fry and stocking the tank with macro shrimp with eggs ,Ive also mixed eggs and brine shrimp in to my blended ice cube feeding blocks as they seem to get excited when the block melts and move around alot..Ive figured my adults have at most six months life span so I would like to get more pipes with eggs soon and try to raise the young to adults 12-14 months
